Description

ELECTRONIC PROXIMITY SECURITY SYSTEM CROSS REFERENCE FOR RELATED APPLICATIONS This non-provisional patent application claims the benefit of the Provisional patent application of E.U.A. No. 60 / 594,186 entitled "Batteryless Electronic Proximity Security Device", filed on March 17, 2005.

FIELD OF THE INVENTION The present invention is generally related to remotely locking and unlocking an area that can be secured. The present invention relates specifically to the evaluation of security codes to determine whether or not to secure an area that can be secured.

BACKGROUND OF THE INVENTION The areas that can be secured, such as containers, rooms, patios and the like, are often secured by a locking device. Blocking devices typically include apparatus and methods for locking and unlocking the device. Normally, methods require that a person seeking to block and unblock a lock is placed very close to the device. For example, a key lock or combination lock requires that a person be close enough to the lock to physically manipulate the lock with a suitable key or enter a combination to lock or unlock the locking device. It is convenient to develop devices and methods to secure or remotely release an area that can be secured. Devices and methods that have been designed and developed to remotely secure or release a commonly assurable area require a power source, typically electrical energy stored in a battery, to lock and unlock a locking device. Such systems may require frequent maintenance and the service time is often limited by the battery life. It is desirable to develop apparatus and methods to remotely secure or release an area that can be assured to limit the amount of maintenance required and that limit the energy needed to energize said apparatuses and methods.

Optionally energy and energy conservation devices and methods are included in the apparatuses and methods described herein. One embodiment of the invention provides an energy conservation system for controlling access in an area that can be secured. The system includes a transmitter, a receiver, a logic circuit, an energy storage device and a locking mechanism. The transmitter transmits remotely a signal that is received selectively by the receiver. The receiver includes an active state and an inactive state. The logic circuit is in communication with the receiver and includes an active state and an inactive state. The logic circuit is in communication with the energy storage device, which is in communication with the locking mechanism. When the receiver receives the signal from the transmitter, the blocking mechanism selectively allows access to the area that can be secured.

DETAILED DESCRIPTION OF THE MODALITIES The detailed description of the present invention simply describes the preferred embodiments of the present invention and is not intended to limit the scope of the claims in any way. In fact, the present invention as described by the claims is broader and unlimited by the preferred embodiments and the terms in the claims have their full ordinary meaning. As described herein, the apparatuses and methods can be designed to remotely lock and unlock an area or space that can be secured, such as, for example, rooms, fenced yards, storage tanks, containers and the like. Said areas that can be secured are normally secured by blocking an access device, such as, for example, a door, a hatch and the like. Devices and methods for locking and unlocking remotely can be configured in such a way that only authorized persons have the ability to lock or unlock the area that can be secured. When a attempt to unlock the area that can be secured, the devices and methods used are subject to an authentication procedure to determine if the area that can be secured should be unlocked. Said apparatuses and methods are normally based on energy, such as electric power, to energize the authentication procedure and the blocking and unblocking of the area that can be secured. The conservation of energy, limiting the amount of energy or power needed to authenticate a user or block and unblock the area that can be assured, can extend the life of these devices and reduce the occurrences of time out of service due to depletion of the power supply. Additionally, conserving energy can reduce the amount of maintenance by limiting the frequency at which a power supply, such as an electric battery, needs to be changed. Figure 1 illustrates a schematic representation of an example embodiment of an electronic proximity security system or assembly 10. The security system 10 includes a space or area that can be secured 12 and an access device 14 by which, the area that can be secured is accessed 12. The terms "secure area 12" and "access device 14" represent a wide variety of components. For the purposes of the description of Figure 1, the area that can be secured 12 will be called a container and the access device 12 will be called a door.

The security system 10 is remote in the sense that an authorized user can lock and unlock the door 14 of the container 12 without having physical contact with the door 14 or container 12. Preferably, a user can lock and unlock the door 14 only when the user is near the container 12 For example, the system 10 can be configured to allow a user to unlock the door 14 only when the user is within a radius of three meters of the container 12 To achieve remote locking and unlocking of the door 14, the system 10 includes a transmitter 16, a receiver 18, a logic circuit 20, an energy storage device 22, an activator 24 and a closing mechanism 26 The method for locking the door 14 begins with the transmitter 16 that generates a signal 28 that can be received by the receiver 18 The receiver 18 receives the signal 28 when the receiver 18 is within the range of the transmitter 16 Com or will be described in detail, the signal 28 contains the information used by the receiver 18 and other elements of the system 10 to authenticate a user and determine if the door 14 is to be unlocked. The receiver 18 is in electrical communication with the logic circuit 20. Once the receiver 18 receives the information carried by the signal 28, the receiver 18 and, optionally, the logic circuit 20 can interpret the information to authenticate the signal 28 as originating from an authorized transmitter 16 or authorized user. The logic circuit 20 is in electrical communication with the energy storage device 22, which is in electrical communication with the activator 24. The activator 24 is coupled to the closing mechanism 26, which physically locks and unlocks the door 14. The activator 24 controls the position of the closing mechanism 26, which determines whether the door 14 is blocked or unlocked. If the signal 28 is authenticated, the logic circuit 20 commands the energy storage device 22 to deliver the energy to the activator 24. This energy energizes the activator 24 to place the closing mechanism 26 in such a way that the door 14 is unlocked . In alternative configurations, the energy storage device 22 can stop energizing the activator 24 or alter the energy delivered to the activator 24 to cause the door 14 to unlock. If the signal 28 can not be authenticated by the receiver 18 and / or the logic circuit 20 does not take actions to unlock the door 14. All procedures of receiving the signal 28, evaluating the information and unlocking the door 14 consume energy and power. The components of the security system 10 can be configured to minimize the use of energy and power. Some areas that can be secured 10 may require unlocking on a few occasions. For example, a secured mailbox can only be unlocked twice a day, once when the postal vehicle delivers the mail and once when the recipient picks up the mail. For the vast majority of the day, these containers may remain blocked. If the receiver 18 and the circuit logical 20 remain active all the time, the energy used to maintain this active state could be wasted, with the exception of the two moments per day when the container 12 is unlocked. To minimize the energy used by the receiver 18 and the logic circuit 20, each is configured to have an active state and an inactive state or dormant state. When the receiver 18 and the logic circuit 20 are in active state, the information of the signal 28 can be interpreted and used to make decisions. When the receiver 18 and the logic circuit 20 are in the inactive state, the information can not be interpreted. In order for this configuration to be useful, the receiver 18 and the logic circuit 20 need to be activated, or moved from the inactive state to an active state, when the information requires interpretation. One method for moving the receiver 18 from an inactive state to an active state is to use a portion of the signal 28 transmitted from the transmitter 16 to activate the receiver 18. A schematic representation of a signal 28 is illustrated in FIG. 2. first portion 30 of signal 28 is an unmodulated sine wave. This unmodulated portion does not carry any information. This first portion 30 is designed to provide power to the receiver 18 to activate the receiver 18 and move it from an inactive state to an active state. Once the receiver 18 is in the active state, the receiver 18 receives a second portion 32 of the signal 28. This second portion 32 of the signal 28 is modulated and contains a first security code that is read and interpreted by the receiver 18. The receiver 18 compares the first security code with a first access code stored in the receiver 18. Optionally, the energy required to interpret the first security code and compare it with the first access code can be derived from the signal 28. This minimizes the energy required from the energy storage device 22 to operate the system 10. If the first security code does not correspond to the first access code, the receiver 18 returns to the inactive state. If the first security code corresponds to the first access code, the user is partially authenticated and the receiver 18 sends a message to the logic circuit 20 to activate the logic circuit 20 and move it from an inactive state to an active state. Additionally, the receiver 18 receives a third portion 34 of the signal 28 and passes that portion 34 to the logic circuit 20. The third portion 34 of the signal 28 is modulated and contains a second security code. The second security code is interpreted by the logic circuit 20 and compared to the second access code stored in the logic circuit 20. Alternatively, the second access code may be stored in a non-volatile memory circuit 36 that is in communication with the logic circuit 20. If the second security code does not correspond to the second access code, the logic circuit 20 takes no action and returns to an inactive state. If the second security code corresponds to the second access code, the user is authenticated completely and the logic circuit 20 sends a message to the storage device of the user. energy 22 to energize the activator 24, which places the closing mechanism 26 to unlock the door 14. Although in the embodiment illustrated by figures 1 and 2 it describes a first and second safety codes, it should be understood that any number of codes Security can be incorporated into a signal. Additionally, the complexity of each security code can be varied to offer an appropriate amount of security. For example, an 8-bit code offers 256 unique codes, while a twenty-four-bit code offers almost 17 million unique codes. Optionally, the signal 28 may include information different from the security codes. For example, in a circumstance where there are multiple authorized users, the signal 28 may include information about the identity of the current users. This information can be stored in the non-volatile memory circuit 36 to form a retrospective access tracking for the container 12. This retrospective tracking can include the time and date of each access, the duration of the access and other different information. This retrospective tracking can be retrieved from the memory circuit 36 as necessary. The information in the retrospective follow-up can be presented through a deployment screen, a printed report, or other methods so that those people authorized by security can see said information. The activator 24 and the closing mechanism 26 can be configured to minimize the energy needed to maintain the door 14 in a locked or unlocked position. If the electronic proximity security system 10 is a mailbox such as the one described above, the door 14 will remain locked for the greater part of the time and will be unlocked for a small part of the time. Under these circumstances, the use of energy can be reduced to a minimum if the closing mechanism 26 is placed to lock the door 14 when the energy storage device 22 is not energizing or supplying power to the activator 24. The use of energy by the actuator 24 may be limited to maintain closure mechanism 26 in a position that unlocks door 14. An example of such configuration is the use of a mechanical spring to position closure mechanism 26 in such a manner that door 14 is locked. When an authorized user requests that the door 14 be unlocked, the energy of the energy storage device 22 can energize the actuator 24 to overcome the force of the mechanical spring and place the closing mechanism 26 to unlock the door 14. Alternatively, the security system 10 can be used in such a way that the door 14 is unlocked most of the time. A mechanical spring can be positioned to maintain the closing mechanism 26 in a position where the door 14 is unlocked. Energizing activator 24 could move latch mechanism 26 to the position where door 14 is locked. The energy storage device 22 may be any device that has the ability to store energy. By For example, you can use a single-use battery or a rechargeable battery. The single-use battery can energize the system 10 until its useful life runs out, at which time the exhausted single-use battery could be exchanged for a new single-use battery. The rechargeable battery can be connected to a power source that recharges the battery. Figure 1 illustrates a solar panel 38 attached to the energy storage device 22. The solar panel 38 transforms natural light into electricity and the electricity generated can be stored in a rechargeable battery 22. The electricity generated by the solar panel 38 passes through an energy conditioner 40 to adapt the energy for storage. The solar panel 38 is an example device for providing power to a rechargeable energy storage device 22. Other devices that can keep a rechargeable energy storage device charged 22, include a windmill and a power supply cord connected to an outlet. Optionally, the energy storage device 22 can be one or more super capacitors. Super capacitors can have a useful life of approximately 12 years. This exceeds the lifetime of a single-use battery or rechargeable battery. The closing mechanism 26 may be composed of standard mechanical components. Referring to FIGS. 3A and 3B, the closing mechanism 26 may include a plunger 42, at least partially positioned in the activator 24 and an L-shaped latch 44 coupled to the door 14. As seen in figure 3A, when the activator 24 is not energized, a spring 46 places the plunger 42 in such a way as to secure the safety 44. As seen in figure 3B, when the activator 24 is energized a force F moves the plunger 42 downwards, with respect to figure 3B. This places the plunger 42 in such a way that the latch 44 is free and the door 14 is free to be opened by a user. This description is exemplary only and the closing mechanism can include any configuration of the components that can secure or free the access device 14 from a secure area 12. Optionally, the electronic proximity security system 10 can including an energy regulator 48 in communication with the energy storage device 22, the activator 24 and the logic circuit 20. The energy regulator 48 regulates the energy flowing from the energy storage device 22 to other components in the system 10 energized by the energy storage device 22. Referring to FIGS. 4A and 4B, a flow chart is shown which represents an exemplary method used in the embodiment shown in FIGS. 1 and FIG. 2. The transmitter 16 transmit signal 28 regulates the intervals in step 50. As seen in figure 2, signal 28 is sent in periods of time. po ti, t2, and t3. During the time period t, the signal is not sent. At the end of the period of time t4, the cycle is repeated by the transmitter 16. The duration of the time periods t-i, t2, t3, and t4, can be any duration. In one example, the durations of the Time periods t, t2, and t3, are approximately 100 to 150 milliseconds each and the duration of time period t4 is approximately 1.5 seconds. Normally, an authorized person carries a transmitter 16. As an authorized person approaches the container 12, the time periods as described, allow the security system 10 to adapt the time to evaluate the signal 28 and unblock the signal. gate 14 before the user reaches the container 12 and attempts to open the door 14. When the signal 28 is transmitted by the transmitter 16, a check is made in step 52 to determine if the receiver 18 is in the signal range 28 If the receiver 18 is out of range, no action occurs. If the receiver is in the range, the receiver 18 receives the signal 28 in step 54. In step 56 a check is made to determine if the receiver 18 is in an active state. If the receiver is already in an active state, the receiver 18 receives the energy and the first security code in step 58. If the receiver 18 is in an inactive or latent state, the first portion 30 of the signal 28 places the receiver 18 in the active state in step 60. The receiver 18 then receives the energy and the first security code in step 58. The receiver 18 evaluates the first security code in step 62. In step 64, it is determined whether the First security code is correct or incorrect. If the first security code is incorrect, the receiver returns to the inactive state in step 66. If the first security code is correct, the logic circuit 20 is activated in step 68. The signal 28 provides the logic circuit 20 the second security code 70 and logic circuit 20 evaluate the second security code in step 72. In step 74, it is determined whether the second security code is correct or incorrect. If the second security code is incorrect, the logic circuit 20 and the receiver 18 return to the inactive state in step 76. If the second security code is correct, the logic circuit 20 instructs the energy storage device 22 to energize the mechanism. blockage in step 78. This causes the secure area 12 to be unlocked in step 80. The logic circuit 20 continues to periodically sample the receiver 18 in step 82. In step 84 it is determined whether the second security code continues to be received by the receiver 18. If the second security code continues to be received, the logic circuit 20 does not make changes. If the second security code is no longer received, the logic circuit 20 instructs the energy storage device 22 to de-energize the blocking mechanism in step 86. The de-energization of the blocking mechanism 26 causes the area that can be blocked. ensure it is secured in step 88. Once the area that can be secured 12 is unlocked, the user can block the area that can be secured 12 by moving the transmitter 16 out of the range of the receiver 18. This can be achieved by simply walking outside of the area that can be secured 12 with the transmitter 16.

Figures 5 to 8 illustrate an exemplary embodiment of a mailbox 100 configured with an electronic proximity security system. As best seen in the perspective view of Figure 5 and the exploded view of Figure 6, the mailbox 100 includes an upper part of the mailbox 102, a lower part of the mailbox 104 and a door 106. The upper part of the mailbox 102 and the lower part of the mailbox 104 are coupled together and the door 106 is hinged to the upper part of the mailbox 102. The door 106 can be opened or closed along the arc A, as shown in figure 5. When the door 106 is closed, an area that can be secured 1 10 is defined by the top of the mailbox 102, the bottom of the mailbox 104 and the door 106. The mailbox 100 includes a printed circuit board (PCB) 112. The PBC 1 12 hosts the receiver 114, a logic circuit 116, a non-volatile memory circuit 118 and at least one super capacitor 120. The infrastructure of the PCB 112 places all the components 1 14, 116, 1 18 and 120 in communication between yes. As best seen in Figure 5, the PCB 112 is mounted on an inner surface 122 or the upper part of the mailbox 102. A cover plate 124 is mounted on the PCB 112 to protect the PBC 112 from deterioration and debris. A solar panel or cell 126 is mounted on an outer surface 128 of the upper part of the mailbox 102 and is in communication with the PCB 112. The solar cell 126 generates the energy that is channeled to the super capacitor 120 for storage. Optionally, they can be incorporated additional renewable energy resources in mailbox 100. For example, additional solar cells can be added to generate more electricity or adjust for geographic areas of the country that may experience less sunlight. The piezo device 129 can be added to charge the super capacitor 120. The piezo device 129 can be added to any location where a force can be applied to the device. Said location is close to where the door 106 makes contact with the upper part of the mailbox 102 from the closure. A piezo device 129 can be configured in such a way that when the door 106 is opened or closed, a force is applied to the piezo device 129. This force generates an electric field that can be tapped, channel the super capacitor 120 and stored for the use future of the mailbox 100. Alternatively, a rechargeable battery can be used and recharged by the solar cell 126 and / or a piezo device, or other renewable energy sources. An activator 130 is mounted on the inner surface 122 of the upper part of the mailbox 102 near where the edge of the upper part 132 of the door 106 is positioned when the door 106 is closed. The activator 130 is in communication with the PCB 112. The closing mechanism includes a plunger 134, located at least partially within the activator 130 (as seen in FIGS. 7 and 8), and a slot or opening 136 in FIG. the edge of the upper part 132 of the door 106. The door 106 is locked when the door 106 is closed and the plunger 134 extends from the activator 130 and is placed in the slot 136 of the door 106, as shown in FIG. shown in Figure 7. The door is not locked when the plunger 134 is retracted in the activator 130 and free from the slot 136 in the door 106, as shown in Figure 8. The transmitter (not shown) of this mode is a radio frequency transmitter. Normally, the transmitter is of a design commonly used by radio frequency identification (RFID) technology. The receiver 114 is an RFID receiver. The transmitted signal is a radio signal, with three portions, similar to the scheme illustrated in Figure 2, and includes the unmodulated active portion, together with a first and second security codes, as described herein. A secured mailbox 100 may be highly desirable. The mail received is often confidential or contains personal information, such as social security numbers and information on bank statements. Outgoing mail is often to the left of the mailbox to be collected by a postal vehicle. Outgoing mail also contains personal and sensitive information, such as checks and personal correspondence. Preferably, a secured mailbox 100 has the ability to protect the delivered mail as well as the outgoing mail. As described above, a mailbox is accessed as rarely as twice a day by two different authorized users, that is, a postal vehicle and the owner of the mailbox. If the postal vehicle had a transmitter that transmitted the appropriate security codes, the postal vehicle could unlock the mailbox 100 to deposit the incoming mail and remove the mail. exit mail and then re-block mailbox 100. Similarly, the mailbox owner can unblock mailbox 100 with a transmitter to deposit the outgoing mail and / or retrieve the incoming mail and re-block the mailbox 100. A postal vehicle needs to service hundreds of mailboxes per day. Having a unique transmitter for each mailbox is impractical. Mailboxes can be configured to be opened by a generic code generated by an RFID transmitter from the post office. This allows the postal vehicle to open many mailboxes with the same transmitter. This system offers efficiency for the postal vehicle and the same level of security as the general current key system used by the US Postal Office. In this system, any mailboxes are configured to be unlocked by a general key used by postal vehicles. The use of RFID transmitters offers efficiencies over generic key systems. Because the transmitter repetitively sends the signal, the mailboxes 100 will open as the postal vehicle approaches the mailbox 100 without any additional affirmative actions, such as using a key to unlock the mailbox. In the embodiment shown, the mailbox 100 is configured in such a way that the door 106 remains closed even when the transmitter of the postal vehicle has the door 106 unlocked. The postal vehicle will need to pull a handle attached to the door 106 to open the mailbox 106. The door 106 can optionally be a loaded spring so that the door 106 closes automatically when the vehicle postal has made the placement of the mail in the mailbox 100 and the recovery of the outgoing mail from the mailbox 100. A postal vehicle simply continues on the route and the movement of the transmitter out of reach of the receiver 114 will block the mailbox 100. The The transmitter used by the owner of the mailbox may not include the generic security code of the post office. The owner's transmitter may contain a security code specific to the owner's mailbox 100. Under this configuration, the receiver 114 and the logic circuit 1 16 recognize at least three codes as correct access codes: a security code evaluated by the receiver 114 to determine if the logic circuit 16 must be activated, a security code from the post office evaluated by the logic circuit 1 16 to grant access to the mailbox 100 to a postal vehicle, and a security code of the owner evaluated by the logic circuit 116 to grant access to the mailbox 100 for the owner. Optionally, the owner's transmitter can send only one command signal, as opposed to sending the signal in a repeating cycle. Because the owner will only use the transmitter once or twice a day, the transmitter can be configured in such a way that a button can be pressed to send the signal. This configuration minimizes the energy used by the owner's transmitter without disturbing the owner.

Although the apparatuses and methods are raised by reference to a mailbox 100, a mailbox 100 is used solely for illustrative purposes. It should be readily understood that said apparatuses and methods can be applied to a wide variety of areas that can be secured different from the mailboxes 100 Such as, for example, a room that can be secured by a door that can be locked, a fence in the yard that can be secured by a door that can be locked, and a warehouse that can be secured by bays that can be blocked Although several aspects of the present invention are described and illustrated in the present description as represented in combination with the example modalities, these various aspects can be realized in many alternative embodiments not shown., any individual form or in vain combinations and the sub-combinations thereof.
